NOTE/WARNING:  This calculator is estimating the fastest
possible pressure based on real world data taken with professional athletes
riding professionally specified and maintained equipment.  This calculator
makes no claims to the compatibility of the rims/tires you have chosen, nor
does it read the internet deeply enough to know the limitations of your setup
as specified by ANY of the manufacturers of the various components in your
setup.  If this calculator recommends pressures that violate ANY of the
limitations of your manufacturer's specifications, you must either change
components or lower your pressures to match those of the manufacturer. 
Note: Tubeless setups, particularly those not adhering to ETRTO, OR hookless setups
are VERY sensitive to pressure and surpassing manufacturers recommended
pressures can lead to unneccessary risks including injury, equipment damage,
and you guessed it: death.
